Vertical Navigation - Copy this React, Tailwind Component to your project

Design a vertical navigation menu for an IELTS preparation app named IELTS Coach. The menu should include the following elements: A header with the title "IELTS Coach" at the top, with IELTS in light blue and Coach in dark blue, conveying a modern and professional look. Four interactive buttons in a column format: Map – A prominent yellow button at the top. Bộ đề (Question Bank) – A light gray button for accessing the question sets. Phòng thi (Exam Room) – Another light gray button for simulating the test environment. Profile – A light gray button at the bottom for user profile management. Ensure the layout is minimalistic with soft colors to maintain a clean, user friendly interface.
